There is a little dent on my ninja tank, but its pointed outwards. Is this normal?
I can't really get pics cause its small.

This is similar to asking a mechanic, "hey, i see this thing sticking out of the engine, is it normal?"

Going to be pretty tough diagnosing the issue without visually inspecting it. Do you have skype and a web camera? If so, you can skype call me and try showing me what youre talking about over the web camera.

It can also be caused by an air bubble or possibly a small piece of debris in the gel coat. You never know when a spec of something is going to stick to it during the curing process.
I've hand a few tanks with a small little bump here or there.
